Honda insiders push for Acura NSX Type R sans hybrid tech

With 500 horsepower on tap from a sophisticated hybrid powertrain, there's plenty to love about the new Acura NSX. If the more performance-oriented elements within the Japanese automaker get their way, it could get even better. Speaking with one of the NSX project's chief engineers Nick Robinson at the launch of the new supercar, Autocar reports that there's an effort underway to develop an NSX Type R. Following a much-loved formula, the more extreme variant would pack even more power than the existing version, unburdened by excess weight. A big part of the targeted weight savings would come from ditching some of the heavier components from the hybrid system. The electric motor at the rear could stay to serve as alternator, starter motor, and flywheel. But the electric motors at the front would go, helping to shed a few hundred pounds. Throw in some lightweight materials and we'd be looking at a considerable weight reduction. It could even integrate some active aerodynamic elements that were excluded from the NSX on the road to production. Though the project may still be a ways off from getting the green light, but Robinson and some of his colleagues are working on prototypes ostensibly to make the case. He and his brother James (a powertrain engineer at Honda) will be driving a pair of NSXs at Pikes Peak this year – one that's as close to showroom stock as the regulations will allow, but the other will be closer to what they have in mind for a Type R. It'll ditch the hybrid system and put an electric compressor in its place to eliminate any turbo lag and produce even more power than the existing model. Now if they can only get the go-ahead from the higher-ups at Honda.

Acura MDX Prototype reveals slick new looks, with Type S close behind

The next-generation Acura MDX is here, almost. This three-row crossover you’re looking at is technically being called the MDX Prototype by Acura, but itÂ’s about as close to production as any prototype can get. And what a looker it is. Acura has followed up the slick TLX sedan with another attractive design. With the MDX now the best-selling Acura nameplate of all time, this one was even more important for Acura to get right. Just like the TLX, it benefits from a much longer dash-to-axle dimension, measuring in six inches longer than the outgoing MDX. The pentagon grille, and Chicane-shaped DRLs in the headlights now grace a much wider car. Acura gave this MDX a wider track and a three-inch longer wheelbase, both aiding in making it appear far more graceful and sporty. Acura clearly isnÂ’t holding much of anything back with this MDX Prototype versus the final production car, and weÂ’re liking what we can see so far. Many of the design elements we liked so much on the TLX are transferred over to this crossover body style, and Acura has done so with class. The MDXs you see here are riding on new 21-inch wheels that are bolted up to a new light truck platform and chassis specifically tailored for the MDX. Acura says it provides for more athletic handling, greater ride comfort and a quieter cabin versus the outgoing MDX. ItÂ’s even more rigid than the RDXÂ’s body. Just like the new TLX, Acura has gone with a double wishbone front suspension design to make the MDX an even sportier driver. ThereÂ’s more excitement in the powertrain options for the new MDX, too. Acura promises a Type S version of the MDX is coming with the same 3.0-liter turbocharged V6 youÂ’ll find under the hood of the TLX Type S. It will make 355 horsepower and 354 pound-feet of torque (same as the TLX) in this application. The standard engine will continue to be AcuraÂ’s 3.5-liter V6 that makes 290 horsepower and 267 pound-feet of torque. Both engines will be mated to AcuraÂ’s 10-speed automatic transmission and send power to all four wheels using the latest fourth-generation SH-AWD system. Not all of the performance details are available yet, but Acura says the MDX can be had with four-piston Brembo brake calipers and comes with a drive mode selector that allows you to adjust ride, handling, steering, suspension and powertrain characteristics. More Type S-specific details will need to wait. The interior matches the exterior for flair and elegance.

2021 Acura TLX Long-Term Update | Tuneful turbo-four soundtrack

I used to be enamored with the turbocharged 2.0-liter engine format. I owned a 2004 Subaru WRX, with its turbo boxer mill, and liked it quite a bit, rough though it could be. Then turbo-fours, often displacing the same 2.0 liters, began replacing heavier and thirstier naturally aspirated V6 powerplants across the industry, and I was on board. Since then, they’ve become much more refined and responsive, all while their often uninspiring soundtracks faded into the background as automakers worked to improve the experience inside the cabin. TheyÂ’ve also become so ubiquitous that, apart from certain standouts like the turbo boxer in the Porsche 718, they ceased to be as exciting to me. Then AutoblogÂ’s long-term 2021 Acura TLX arrived in my driveway, equipped with a 2.0-liter turbo I4. I was excited about the styling and the handling, but I didnÂ’t expect this four-pot to make a huge impression on me. The first time I opened her up under wide-open throttle, though, I was pleasantly surprised. This 2.0TÂ’s 272 horsepower and 280 pound-feet of torque are ample motivation for this sporty sedan, even with all-wheel drive and a 3,990-pound curb weight. It wonÂ’t knock your hat into the back seat, but itÂ’s quick enough, especially in Sport mode. The thing that really won me over with this 2.0T, though, is the sound. Ripping to this thing's 6,800-rpm redline produces a melodious song that sounds a lot more exciting and expressive than most other fours. The cherry on top is the punctuated hiss of the turbo releasing its pressure when you get off the throttle. The amplitude of the engine note is manipulated using AcuraÂ’s Active Sound Control. As an Acura spokesperson explained it: “Active Sound Control uses the TLXÂ’s speakers (whether audio is playing or not) to add sound (same-phase or reverse-phase) to the cabin that smooths the sound of the engine heard inside the cabin. Engine noise doesn't increase in a linear way with rising revs; instead there can be many resonances that create peaks and valleys in the sound pressure level and an uneven sound. The level of ASC is tailored to each drive mode (Comfort, Normal and Sport).” Put another way, ASC is basically an electronic filter that can deaden or amplify the sound and smoothen it out, similar to how active suspension damping adjusts to the situation and drive modes to either let in more or less road feel, while actively eliminating the harshest of vibrations.
